Application filed July 1, 1914. Serial No. 848,352.

To all whom it may concern Be it known that I, RUDOLPH LINDEMANN, acitizen of the United States, and a resident of the borough of Bronx,city, county, and State of New York, have invented new and usefulImprovements in Storage Bins or Bunkers, of which the following is aspecification.

This invention relates to storage bins or bunkers of the kind employedfor storing coal, grain, etc., and has for its object to provide a binwhich may be cheaply and quickly erected from stock constructionmaterials and largely from parts requiring no special fitting.

A further object of the invention is to provide a bin which willvsustain a large load but which is of comparatively light construction.

A further object of the invention is to provide a bin which will bethoroughly protected from corrosion from destructive elements that maybe present in the material stored.

With the above objects in view my invention consists in the improvedconstruction hereinafter described and illustrated in the accompanyingdrawings, in which,

Figure 1 is a side elevation showing a portion of a bin of indefinitelength; Fig. 2 is a transverse sectionalview upon an enlarged scale;Figs. 3, 4, and 5 are detail views which will be later described; andFig. 6 is a detail of a modification.

' Referring now to the drawingslindicates the supporting columns whichmay be of structural iron or steel, from the top of which the bin properis suspended. Attached to the top of the columns are plates 2 in whichare supported the continuous, inclined plate girders 3 extendinglongitudinally between I the columns 1. The frame structure is is formedof reinforced concrete of a special construction to be described, andshaped to provide mchned sides, forming practically extensions of thegirders 3, and connected by a curved bottom.

In the preferred construction as illustrated in Fig. 2 the plate of thegirder 3 extends beyond its base angle 3 and clamped to this extensionat suitable intervals along the girder are clevises 7 in which arescrew-threaded the ends of the suspension rods 8 which support the wallsof the bin.- The rods 8 are bent like the ribs of a boat and extend fromthe girder on one side to that on the other, the construction of coursebeing identical on each side; Supported on the rods 8 and attachedthereto by clips 9 is a continuous sheet of metal fabric 10, such asemployed in reinforced concrete construction;

In my improved construction any. ap-

which consists of alternate widths of-expanded metal having betweenthese widths ribs 10 formed by crimping an uncut width of the metal. Theclip 9 which I have shown is especially designed for attaching this formof fabric to the rods and comprises a flat splitring for encircling therod and an upstanding tongue 11 adapted to project between'the walls ofthe rib to which it may be fastened by a suitable pin or by merelypunching through theribfand the tongue, so that the bur of the rib willengage the hole in the tongue.

The clips 9 may be formed by stamping out the sheet metal and are veryquickly applied without special tools for the purpose. The function ofthe clips is merelyto hold the fabric in place until the cement isapplied, and as they support none of the load, they may be light enoughto bend around the rod by hand. After the fabric is fastened in placethe interior of the bin is lined with a thick coat ofcement-mortarorconcrete 12 and is plastered outside between the rods 8so thatthe fabric is entirely embedded in V the cement.

channelsand embedded in the cement 12.

Attached to the inner face of the channels is a sheet of metal fabricwhose lower edge terminates just 'above the level of the fabric of 'theside walls which is bent up at, the

end shown in Fig. 4 to form an overlappingjo-int with the; end. sheet.The end sheet of fabric maybe fastened to the channelsiin any approvedmanner, for instance,

' bys uit ableclips 17 somewhat similar to the clips 9 but having asingle fiat tongue adaptedtobend under thejflat web of the channelinstead of aroundthe'rod 8; A fiat stay 18 may be attached to the fabricat the other side of the channel to holdthe fabric against lateral,movement. Theend wall: is plastered on both itsinner and outer surfacesin the same manneras the side walls, so that he re ur e .O -t e bun e wh .0 1-

The expandedmetalfabric may be had in bales area of the fabric when spread out. The

rods 8 need not be bent to accurate shape bilit are preferably shippedsimply bent in a loop and withtheir ends attached together. The'attaching clips 9 may be set at any point along the rodsor fabric, sothat no special fittingof thepartsis required except in the ordinarystructural iron work ofathe supp' ttiesir ms 'W en e od e pp their endsare easily drawn apart and all the rods will have substantially the samecurve.

Having thus described my invention, what I claim and desire to secure byLetters Patent is:

1. In a suspension bin, the combination of a supporting frame workhaving its upper longitudinal edges formed of girders, a series ofparallel suspension rods connected at each end to the opposite girderswith their ends extending downwardly and inclined toward each other andhaving the intermediate connecting portion curved, an open mesh fabrichaving stiffening ribs at intervals supported on said rodswith the ribsextending longitudinally of the bin, connecting members rigidly attachedto said ribs and encircling said rods, the portion of the connectingmembers encircling the rods being adapted for cooperation with the rodsat any point in their lengths.

2. In a suspension bin, the combination of a supporting frame workhaving its upper longitudinal corners formed of. inclined girders, aseries of parallel suspension rods connected at each end to the oppositegirders and-extending substantially in the direction of the inclinationof said girders with the intermediate connecting portion curved, an openmesh fabric having stiffening ribs at intervals supported on said rods,clips connecting said fabric and said rods comprising a part attached tosaid ribs and a bifurcated part adapted to loosely encircle said rod atany point in its length, and a covering layer of mortar or concretelaidon said fabric.
